MACHINE FOR DYEING AND WASHING WOOL AND COTTON.

SPECIFICATION forming part of Letters Patent No. 338,438, dated March23. 1886.

Application filed March 3, 1884.

To all whom it may concern:

Be it known that we, WRIGHT POLLARD and Moses POLLARD, both ofPawtucket, in the county ofProvidenceand StateofRhodeIsland,haveinvented certain new and useful Improvements in Machines for Dyeingand Washing WVool, Cotton, &c., of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part of this specification.

Our invention relates to the vats employed in dyeing and cleaning loosecotton or wool, and particularly to such devices for feeding thematerial through the vats, the object of our invention being tothoroughly open the material to the action of the liquid, and yet avoidany injury to the material.

To this end our invention consists in the peculiar and novelconstruction of the feedroll, and also in the novel arrangement of thevat and its sieves, as hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a plan view of our improvedvat. Fig. 2 is a vertical longitudinal section of the same on the line 22 of Fig. 1. Fig. 3 is a perspective view of a fragment of thefeed-roll, showing its scalloped vanes. Fig. 4 is a vertical sectionalview of the vat, showing one of the screens G. Fig. 5 is a detailed viewof said screen.

In the said drawings, A designates the vat, which may be either of theform shown or of any other suitable or preferred form, as shown, theends of the v'at being rounded to facilitate the circulation of thematerial within the vat. Upon the bottom of the vat, and at one side ofthe same, is placed a /\-shaped partition, B, while above the partitionB is placed the cover 0.

Near each end of the vatA is placed a steampipe, D, which throws jets ofsteam into the vat.

Between the partition B and the cover 0 is placed the feed-roll E,whichis mounted upon the shaft 6, journaled upon the sides of the vat. Theshaft 6 also carries a revolving screen, F, and is provided with apulley, c, by means of which power is transmitted to the shaft for thepurpose of revolving the feed-roll E and the screen F.

Between oblique guides c c, placed in pairs Serial No. 122,770. (Nomodel.)

at each end of the cover 0, are placed the screens G, and behind eachscreen is an outlet, 0, for water and dye thrown off through the screensG by the roll E. r

The partition B is provided with the steamtraps b I), having steaminlets 6 b from which pipes lead to a steam-generator, the top of thetrap 12 being covered by oblique plates b, while the opening of the trapb is covered by ascreen, 11 These traps serve to admit steam intocontact with the loose material passing through the vat, while theoblique plates 1) and the screen 11 prevent the material from enteringthe traps and becoming clogged therein. Any of the liquid which may passbetween the plates b and through the screen I) is instantly blown backagain by the currents of steam escaping from the traps b I). These trapshaving no communication with the space between the partition B and thebottom of the vat, water and steam are excluded therefrom.

H designates the vanes of the feed-ro1l,which are secured to theperiphery of said roll in such manner as to project radially therefrom.The outer edge of each vane is scalloped, as at h, so that the vanes maytake hold of the material and open it to the action of the dye orliquid,and yet not lacerate or otherwise inj ure the material.

The operation of the machine is as follows: The liquid is placed in thebottom of the vat A, and steam is forced through it from the inlets 1) band steam is also forced into the vat upon the liquid and materialthrough the pipes D D. The material having been fed into the vat at theleft-hand side, the roll E, revolving in the direction of the arrow,carries the material through the liquid and up over the apex b of thepartition 13. The material then falls down upon the right-hand end ofthe vatbottom, is then guided by the rounded end of the vat to therevolving screen F, and is then caught by the revolving screen F andlifted out of the liquid, and then again dropped into it. Theseoperations are continued till the liquid and steam have acted upon allparts of the material. by the roll is thrown out through the screens G,and escapes through the outlets 0'. After a vat full of material hasbeen thoroughly treated the machine is stopped, the material The liquidwhich is carried upremoved, and a second vat full of material is plac din the liquid.

Having thus described our invention, Claim 1. The roll E, provided withthe scalloped radial vanes H, as and for the purposes described.

2. The vat A, provided with the partition B and the traps b b, as andfor the purposes specified.

3. The combination of the vat A, having the partition 13, the traps b b,the deflectors If, and screen b the cover 0, the screens G, the axle e,and the roll E, having vanes H, arranged and constructed as and for thepurposes set forth.

4. In a vat, the combination, with a rotating cylinder having scallopedor indented radial vanes on its periphery and located near the top ofand to one side of the vat, and the inverted-\l-shaped partitionsituated directly below the cylinder,- of a screen revolving by the sideof and on the same axis as the cylinder, substantially as and for thepurpose described.

5. The combination, with the vat A, of the cylinder E, the fan F,revolving side by side on the same axis, e, the partition B, having thetraps b b, the injecting-pipes b b and D D, the cover 0, having theguides c c, holding the screens g g, and the outlet-pipes c c, for thepurpose specified.
